IF. Trump is impeached (indicted) by the House and acquitted by the Senate, then loses re-election, could the charges developed and explained by the House be used in federal court against ex-president Trump? Or does the Senate trial (of a sitting president) open the double jeopardy box?
Impeachment is a political – not legal – process.
Indeed, a president can be removed from office via the impeachment process absent alleged criminal wrongdoing.
A president removed from office via impeachment because of alleged criminal activity can be subject to criminal prosecution, but that’s unlikely at the Federal level.
Justice would never indict a president – sitting or former – as it would establish a dangerous precedent.
Indictment of a former president at the state level would be more likely.
‘Conviction’ by the Senate is not a criminal conviction, as the president’s life, liberty, and property are not in jeopardy; a president removed from office via impeachment would be at liberty to return home to write his memoir and plan for his presidential library.
